Frame Conectors instructions

Bought the plumb bob and spent all day doing the measurements. from segment, diagonally to the rear is with in spec. front of rear spring perch, diagonally to rear leaf spring mount bolt is 1 and 3/4 inch off.

What is strange is both side are exactly off the same! Spec said 76.04(plus or minus .25) and both side are 74" 5/16 exactly. I can't be leave that both front segment, of the rear sub frame, would being bent the same amount :scratch:

any body have access to a 70 ply body manual.
The one i have is for a 71. I have been told that the 70 and 71 Barracuda's were the same............but now i question that.
